The Return of the Armor Legend

Fang Guang accidentally transmigrated into the world of Armor Hero, but not the Armor Hero series he knew. This was a hundred years after the Xingtian Armor sealed Lufa, and several generations of armor summoners had come and gone. What will happen when the Nawa, Yanlong, and Xingtian armors all come together? Think that's all there is to it? The protagonist has no idea that an even greater danger is on its way!
